Microgestin 1/20 Fe Am I protected ?

I was on the pill for a whole month and a half but decided to start another form of birth control . I went to my doctor and decided to get on the shot. Everything was perfect for a whole month but i started gaining weight and didn't like it. I was suppose to follow up for another dose of the shot on August 19th. From Aug13th till now I haven't had any unprotected sex because according to the appt the shot was already over ... I decided to go to the doctor to follow up for another dose of pills instead of the shot because I didn't have time to go get the shot again . I been taking the pill for more than a week now but I didn't consult my doctor about going back to the pill after the shot ... Am I protected ?
